Multiple Rocket Launchers

[Col_Travis]

I have noticed that the Russian Federation BM-27 Uragan & BM-30 Smerch fire several diferent calibre rockets and the Brazilian Astros II only fire one , this is false! As of 2009 only two MRLS systems can fire multiple calibre rockets, the US M270 (German MARS) & Brazilian Astros II system. The BM-27 Uragan can oly fire the 220mm rocket and the BM-30 Smerch 300mm rockets, they do not have modular rocket packs, only the M270/MARS & Astros II have them.
